I agree with you, especially since it's only affecting the ones getting the most light. I know lumens isn't the greatest gauge but the ones with the most light are getting 160,000-180,000 lumens. The light are gar enough away though so no light burn. What I dont understand is why are a few away from the lights dark green like they had too much nitrogen. They all get the same amount of nutes.
Hey Logan, I think I'm going to start a new thread in the sick plant section tommorow. Apparently this is normal but in the late flowering cycle like week 7 or 8 and is actually a good thing because it means you wont taste the nutes in the buds when smoked. I was looking at threads where this happens in late flowering and the buds are the same size as mine are! Mine are only starting there 5th week tommorow so they have another 4 to 5 weeks left! I can only imagine how big these buds will get in the end!
I really dont think giving them more nitrogen will help. I give them 1 teaspoon of grow big and the max dose is 2 teaspoons. Plus they get a little nitrogen from big bloom, tiger bloom, and beastie blooms which I'm currently giving them. Something else has to be going on. Its also not affecting all the plants just the ones with the most light. In fact a few on the outside are dark green like they have had nitrogen toxicity. Very strange behavior.
Too late
Ya I'm almost positive it's a pk issue, it has all the signs including purple stems but that could also be genetics since it is grand daddy purple. I have 5000 watts of light and it's mainly the ones right under the lights. I'm going to double there bloom nutes. It's ok though I'll still be under the max dose. I just think they really need it. As for the dark green outside ones I looked it up and it says those are the first signs of a pk deficiency or bluish and shiny. If this was like week 7 or 8 I wouldnt really care in fact I read it's a good thing but I just started week 5 so I think something needs to be done. Thanks again and I'll let you know how it goes!
Thanks Porky! Just curious are you using a lot of lights too? Maybe it's a pk issue like I might have, you should post some pics of your girls.
Did you say your humidity is 70%? If it is that's way too high and may be apart of your problem.Too late
I went and took 2l of feed water (1.3EC (0.3 is calmag)) and I added another 0.3 of calmag (so 1.6). I did that the past two days...
It is an indica dominant straint, coco, PH 6. EC 1.3. 82F CXB 3590. 70%h. 800umol avg. plants look healthy but they look hungry...especially N, their leaves are fading faster than I would like...I could add more bloom nutes which contain some N in it, but I thought just calmag would do the trick...
thanks!
I will see how this plant turns out and will adjust accordingly. Its a fine balance, you want them too fade but not too fast....Well it sounds like you know what your doing. Ya your right you want them to fade yellow just not too fast and not too early. You would be the best judge of your plants!Thanks for your reply Steve!
The humidity is relative too the temprature, 82 F @70% humidity is the similar to 77F @ 50% humidity. I can assure you, even 80% humidity @84F is perfectly acceptable.
I am running around 1,000Umols. I dont think it is a PK issue, as the only issue seems to be the plants are fading yellow faster than I would like. I believe it either needs more food or perhaps it is fading fine and im just being a bit over protective
Peace man!
Ill search for some links for you.
Oh ya I've heard when running higher co2 levels you want higher humidity. I'm not running co2 though. I probably would of if I understood how to use it but I dont lol. I currently keep my day temps at around 75-78f and night at 62-65f. My humidity with lights on is 45-55 and lights off about the same.
